That's not quite how it works. Where there are laws governing such things,
the buyer will have the house inspected to be sure it meets code. It might
escape notice; it might not. Or, in the event of a claim, the insurance
company might find that the non-compliant condition was causative.

What buyer? Do you have people inspecting your house all the time in case
they want to buy? Seems to me, if you are going to sell you'd probably
start dismantling the shop anyway and can remove wiring easily.

As for the insurance claim, something has to go wrong first. Then it has to
be related.
